What Are Those Colors You See When You Rub Your Eyes Paul Cj Taylor
In the 1600s, Isaac Newton conducted a series of experiments to better understand the lights and colors that sometimes appear when your eyes are closed. If you’ve ever sat around an evening campfire or unintentionally glanced at the Sun, you may have noticed illuminated patterns briefly dance along your vision. So how do these visual illusions form? Paul Taylor explores the science of afterimages.
Your Brain Can Solve Algorithms David J Malan
An algorithm is a method of solving problems both big and small. Though computers run algorithms constantly, humans can also solve problems with algorithms. David J. Malan explains how algorithms can be used in seemingly simple situations and also complex ones.
The Genie of Polarisation How Can We Get it Back in the Bottle Kris De Meyer Tedxlondon
We live in an increasingly polarized world — how did we get here? Dr Kris De Meyer explores how people become entrenched in their views and the gridlocked debates these opinions lead to.

The Pangaea Pop Up Michael Molina
The supercontinent Pangaea, with its connected South America and Africa, broke apart 200 million years ago. But the continents haven't stopped shifting -- the tectonic plates beneath our feet (in Earth's two top layers, the lithosphere and the asthenosphere) are still traveling at about the rate your fingernails grow. Michael Molina discusses the catalysts and consequences of continental drift.
When Will the Next Mass Extinction Occur Borths D Emic and Pritchard
About 66 million years ago, a terrible extinction event wiped out the dinosaurs. But it wasn’t the only event of this kind -- extinctions of various severity have occurred throughout the Earth’s history -- and are still happening all around us today. Borths, D'Emic, and Pritchard give a quick history of mass extinctions.
